Tectonic Elements TEAX25C10-8/SP 25mm High Power 8 Ohm Frog Exciter

Tectonic's TEAX25C10-8/SP Frog Exciter turns virtually any solid object into a speaker, when attached, by vibrating it at speeds of up to 20,000 cycles per second. The vibrations modulate the air, which is then decoded by the brain as sound. Test the limits of your imagination.

Place the Tectonic Frog Exciter on a window, under a desk, in an overhead cabinet, behind picture frames, inside cans, behind paper plates, inside binders, cardboard, scraps of wood and even the box they come in! The sound quality will surprise you no matter where you place them. Included 3M adhesive pads offer long-lasting attachment that sets up in seconds. 7 ft. long attached speaker wires for amplifier connection.

Reviews

Tectonic Elements TEAX25C10-8/SP 25mm High Power 8 Ohm Frog Exciter is rated 5.0 out of 5 by 3.

Rated 5 out of 5 by nappyaudio from completely blown awayI bought these for a client that wanted to add sound in their kitchen just for basics like watching the tv that is in the living room without having their wife crank up the volume. First attempt was to mount them to the granite countertops. Be aware, although these can basically vibrate anything, the easier it vibrates, the louder you will hear it. Next attempt was the kitchen sink. Wow!!! What a difference. These even sounded decent with music, however, the sound was a little tinny sounding probably because of the shape of the sink and the fact that it was stainless steel. Overall, the client was super happy and how can you beat the cost? No fishing wires to the ceiling, no cutting holes... Just a stunning solution. Will absolutely be buying these again when needing background sound.

Rated 5 out of 5 by Fixer from Perfect for hidden speakers in drop ceilingsI tried two of these on two 24" X 24" ceiling tiles in a suspended ceiling as the person wanted totally hidden speakers.All I can say is I am simply blown away by the sound.I plan on finishing the job with four more of these.If powering these transducers with anything over a 10 watt amp add an 8 ohm 10 watt resistor in series with each one if using one per channel. For two per channel put them in series. For three per channel add a 10 ohm 10 watt resistor in series with each driver and parallel them if your amplifier can handle a 6 ohm load.The resistors are for impedance matching and to help prevent overpowering the transducers.One more tip. If mounting to a ceiling tile be sure the back is cleaned of all dust and also to be absolutely sure of a long lasting hold (these do vibrate a good bit at higher power levels) you can also use some 5 minute epoxy to help further secure the transducers.These also should work quite nicely on 24" X 48" ceiling tiles as well.The possibilities with these are endless.

Rated 5 out of 5 by Old school audio man from Great concept ... amazing resultsI recently bought a pair of Bertagni "panel" (SM-100's)speakers very cheap. These speakers are a specially formed styrofoam panel with different thicknesses to produce different frequencies.They used a normal voice coil glued to the styrofoam, and a magnet structure mounted to an I-beam.The voice coil was shot.I trimmed off the voice-coil with a dremel tool and simply replaced the magnet with the exciter.It fit EXACTLY in the hole left by the removed magnet, and performed better than the voice-coil designIf you have Bertagni's .... replace the bass driver with these and WOW !!

what kind of amps are people using with these? I'm looking for one to try out the technology that won't blow my budget.

There are many amplifiers that will work well for these exciters. One of our best sellers is the Lepai LP-2020A+ below.http://www.parts-express.com/lepai-lp-2020a-tripath-class-t-hi-fi-audio-mini-amplifier-with-power-supply--310-300

How many exciters are in the package for $19.25?

more expensive sound exciters say only one per package but this one is rated for higher watts so i am wondering if that price is only for one. Thanks.

Asked by: ricky jay

Price is for one unit. Typically you would use two for stereo. If you have a very large surface you can use multiples to take more power and increase sound output.

Application ...

Has anyone tried these as replacements for the drivers in Bertagni panel speakers ?

Asked by: Old school audio man

I assume you have a pair of Fisher model PL-6-U panel speakers. These speakers were a real innovation when they were introduced. The sound they created was not amazing, but their unique thin panel design was such a novelty that they attracted a market for them. If you were an audiophile, you didn't appreciate them.The HiWave HIAX25C10-8/SP 25mm High Power 8 Ohm Frog Exciter is a totally different concept and technology than the PL-6-U. The PL-6-U used two plates each as a pole and the entire plate vibrated when signal was applied thus creating sound.The FZrog Exciter is basically a voice coil in a frame that induces vibration and movement in whatever it is secured to. The glass, box, wall, door or whatever becomes the cone or panel. Generally the sound will depend greatly on what that panel or cone is.As an example, a 4 x 8 sheet of plywood will be better than a whole tree. A glass window will have better high's than a box which would be louder have more bass.To answer your question, I have no idea what kind of panel the Bertagni panel would make, but if you find that they do not make a good one, secure the Froggs to the walls behind them and enjoy, because life is too short to not have what you want even if you have to fake part of it.Good Luck
